BAEZA, Carlos M; RUIZ, Eduardo y TORRES-DIAZ, Cristian. The karyotype of Chaethanthera renifolia (J. Remy) Cabrera (Asteraceae). Gayana Bot. [online]. 2010, vol.67, n.2, pp. 246-248. ISSN 0717-6643. doi: 10.4067/S0717-66432010000200012.
The karyotype of Chaetanthera renifolia (J. Remy) Cabrera from Chile was examined. The species has 2n = 2x = 44 chromosomes, with lm+ lst + 2st-sat+ 17t+ lt-satchromosomes. The reported karyotype is bimodal and very asymmetric (AsK % = 86.6, TF % = 13.4 and Syi % = 15.5). These results are indicating that this species has the highest known chromosome number of the genus so far and the most asymmetrical karyotype of the group.
